Description

High heat radiation pencil formula terminal box
Technical field
The utility model relates to a kind of photovoltaic component terminal box, particularly a kind of pencil formula photovoltaic component terminal box of built-in heat abstractor.
Background technology
Solar photovoltaic assembly terminal box is between the solar cell array of solar module formation and the connector between solar charging controller for electric consumption, is a cross-cutting comprehensive design that collection electrical design, Machine Design combine with material science.Solar photovoltaic assembly terminal box is extremely important in the composition of solar components, and Main Function is that the electric power that solar cell is produced is connected with outside line.Terminal box sticks together by the backboard of silica gel and assembly, and the lead-out wire in assembly links together by the internal wiring in terminal box, and internal wiring and External cable link together, and makes assembly and External cable conducting.In terminal box, have diode, Assurance component can normally be worked when being in the light.
Current photovoltaic component terminal box major part is the mode that adopts diode to stagger and arrange, the equal integrated installations of accessory such as diode binding post are inner at box body, the drawback that this assembling mode exists is the easy temperature distortion of diode adstante febre box body, in order to improve the phenomenon of temperature distortion, the utility model adopts heat abstractor to contact laminating with diode face, so just can strengthen the heat radiation of terminal box, and the distortion that keeps from heat.The profile of terminal box has adopted the structure of pencil formula to save the materials amount of box body itself simultaneously, can also reduce the length of cable.
Utility model content
The utility model object is to provide a kind of saving raw material, the stronger a kind of solar photovoltaic assembly terminal box of dispelling the heat.
In order to solve the problems of the technologies described above, the utility model has adopted following structure:
A photovoltaic component terminal box, comprises box body and base, and described box body is connected with base.Between box body and base, many group binding posts of arranging, are connected by one or many diodes between every two binding posts, play bypass protection effect.Every three or many diode correspondences and a heat abstractor laminating, play heat radiation.Every binding post correspondence is connected with the convergent belt on photovoltaic module, use thermal grease by binding post and diode package, when diode operation febrile state, the heat of diode can pass on box body and base by binding post, heat abstractor, thermal grease in time.
Described photovoltaic component terminal box, is characterized in that box body side is provided with little lid, and capsule is built the effect of being convenient to observation and installation and maintenance.
Described photovoltaic component terminal box, adopts welding connecting mode between binding post and convergent belt.
Described photovoltaic component terminal box, the connected mode that adopts riveted joint soldering to reinforce between binding post and cable.
Described photovoltaic component terminal box, adopts electric resistance welding or soldering connected mode between binding post and diode.
Described photovoltaic component terminal box, the mode of employing face contact between diode and heat abstractor.
Described photovoltaic component terminal box, adopts ultrasonic bonding to be connected to a fixed between box body and base.
The beneficial effects of the utility model: product structure is small and exquisite, cost is low, good heat dissipation effect.
